DCR Injection Pump Conversions
Diesel Engine Repair — Cheyenne, WY
The CP4 injection pump fitted to many late-model diesels has a well-earned reputation: when it fails, it can send metal debris through the entire fuel system — injectors, rails, lines — turning one failed pump into a repair bill north of $10,000. A DCR pump conversion replaces the CP4 with a robust pump design built to survive American diesel fuel.
Trevor installs complete DCR conversion kits: pump, hardware, and everything needed to retrofit your truck properly. For a truck you plan to keep — especially one that tows or works — the conversion costs a fraction of what one CP4 grenade event does.

- Complete DCR pump conversion installs
- Eliminates the CP4's catastrophic failure mode
- Protects injectors, rails and lines from debris
- Ideal for towing, ranch and high-mileage trucks
- Honest advice on whether your truck is a candidate
Diesel Diagnosis Done Right
- Verify and inspect
Every diesel complaint starts with reproducing the symptom and a physical inspection — leaks, soot trails, boots, clamps and wiring.
- Test the systems
Compression tests, fuel system diagnostics and turbo checks isolate whether the problem is mechanical, fuel, or air.
- Confirm before replacing
Injectors, pumps and turbos are expensive. Nothing gets replaced until testing confirms it failed.
- Fix it for the long haul
Where a known weak point exists — like CP4 injection pumps or grid heater bolts — Trevor will tell you about the proven prevention options.
